ribosome inactivating protein/ジャガイモ

ME(1), a type I ribosome-inactivating protein (RIP), belongs to a family of enzymes long believed to possess rRNA N-glycosidase activity directed solely at the universally conserved residue A4324 in the sarcin/ricin loop of large eukaryotic and prokaryotic rRNAs. We have investigated the effect of

To develop an antiviral agent and virus-resistant plants, a cDNA clone encoding Phytolacca insularis antiviral protein (PIP) was isolated from a cDNA library constructed with poly(A)+ RNA purified from leaves of P. insularis. The PIP cDNA contains an open reading frame encoding 307 amino acids. The

OBJECTIVE To engineer broad spectrum resistance in potato using different expression strategies. RESULTS The previously identified Ribosome-Inactivating Protein from Phytolacca heterotepala was expressed in potato under a constitutive or a wound-inducible promoter. Leaves and tubers of the plants

Ribosome-inactivating proteins (RIPs) are N-glycosidases that remove a specific adenine from the sarcin/ricin loop of the large rRNA, thus arresting protein synthesis at the translocation step. In the present study, a protein termed tobacco RIP (TRIP) was isolated from tobacco (Nicotiana tabacum)

Extracts of Mirabilis jalapa (Nyctaginaceae), containing a ribosome inactivating protein (RIP) called Mirabilis antiviral protein (MAP), were tested against infection by potato virus X, potato virus Y, potato leaf roll virus, and potato spindle tuber viroid. Root extracts of M. jalapa sprayed on

We have recently described a novel strategy for engineering resistance to African cassava mosaic virus (ACMV) in transgenic Nicotiana benthamiana plants using a virus-inducible promoter to control the expression of a plant ribosome-inactivating protein (RIP) transgene (Y. Hong et al., Virology 220,

Preventive Human Papillomavirus (HPV) vaccination is an expensive practice and it may be an insufficient tool to tackle cervical cancer worldwide. Therapeutic intervention is seeking for safe/effective vaccines inducing the activation of CD8+ cytotoxic T lymphocytes (CTLs) that is required to clear
